Venturi Scrubber Design Calculation Xls Upd Fix May 2026

To build an accurate design spreadsheet, several critical variables must be accounted for:

) is the most important factor in determining the operating cost of the scrubber. The most common correlation used in design calculations is the Johnstone equation or the Calvert modification.

A modern "upd" (updated) Excel tool for Venturi design should be structured into clear input and output modules: venturi scrubber design calculation xls upd

Even a perfectly designed Venturi scrubber requires regular monitoring. Key performance indicators (KPIs) to track in your spreadsheet include the pressure drop stability and the liquid nozzle pressure. An updated design tool should also account for "evaporative cooling" effects if the inlet gas is significantly hotter than the scrubbing liquid, as this affects the actual gas volume inside the throat.

The volume of scrubbing liquid injected. To build an accurate design spreadsheet, several critical

Enter gas temperature, pressure, moisture content, and particle size distribution.

Calculate the required throat area based on a target velocity. Key performance indicators (KPIs) to track in your

Usually measured in Actual Cubic Feet per Minute (ACFM).

The core of the design process focuses on determining the throat velocity and the liquid-to-gas (L/G) ratio. High throat velocities increase the relative velocity between the gas and liquid droplets, which enhances particle collection through inertial impaction. However, this also significantly increases the pressure drop across the system. Key Calculation Parameters

Use built-in lookup tables for gas density and viscosity based on the inputs.
